  Mechanical movements, including focus, reduction and enlargement ratios are achieved by hand adjustment. Image magnification is determined by the extension of the bellows and relative position of lens and camera.  With a 75 mm lens, ratios of 1:4 trough 4:1 are possible, providing a range for optical zoom, pan, cropping, split screen effects and format reduction or enlargement. Focus is done through  the camera viewfinder. When precise  alignment and focus is required, use 90 degree prism to observe actual  image on camera gate.
The lens and camera axes are tracked and located by fine-pitch lead screws, using graduated hand wheels. Exposure is controlled by the iris, filters and programmable exposure time control. Fades and dissolves are accomplished by using the combination of variable shutter, iris and light dimmer or a combination of ND filters. Colors are corrected by color printing filters.  Synchronized printing speed is 38 frames-per-minute.
Camera rewind speed is 160 frames per-minute. K107 is designed for Bolex H16 Rex 4 & 5  cameras.
